Since new analogues of riboflavin have been synthesized which inhibit the growth of rats and of microorganisms which require riboflavin (l-3), it was decided to test the effect of some of these compounds upon the utilization of riboflavin and flavin adenine dinucleotide (FAD) for growth of Lactobacillus casei. Other compounds structurally related to riboflavin were also studied. It has been sho...

Several Lactobacillus casei strains are used as probiotics. L. casei strain Z11, isolated from a human colon biopsy sample, has been suggested as a probiotic candidate based on promising properties in vitro Here, we present a 2.74-Mbp high-quality draft genome sequence for this strain.

Hydrolysates of cod viscera were tested as an alternative to commonly used complex nitrogen sources (peptones and/or extracts) for the type strains of the lactic acid bacteria Lactococcus lactis, Lactobacillus acidophilus, Lactobacillus helveticus, Lactobacillus casei, Lactobacillus sakei and Pediococcus pentosaceus. Comparative studies with MRS-like media containing different nitrogen sources ...

Lactic acid bacteria (LAB) were isolated from different fermented dairy food and identified as Lactobacillus fermentum, Lactobacillus plantarum, Lactobacillus casei and Lactobacillus brevis. The cell free supernatant of the selected Lactic acid bacteria were able to inhibit the growth of all organisms, used in this study (E. coli, Klebsiella, Pseudomonas, Streptococcus, Proteus). The antibiotic...

Probiotic microorganisms such as lactic acid bacteria (LAB) exert a number of strain-specific health-promoting activities attributed to their immunomodulatory, anti-inflammatory and anti-carcinogenic properties. Despite recent attention, our understanding of the biological processes involved in the beneficial effects of LAB strains is still limited. To this end, the present study investigated t...

background staphylococcus aureus (s. aureus) is the most common pathogen responsible for osteomyelitis. conclusions parenteral administration of viable l. casei inhibits s. aureus-induced infection as shown by the bacteriologic analysis, but makes no difference to the radiological :union: rates. this could be the first step towards developing an effective, biologic adjunctive therapy for the ma...

gamma-amino butyric acid (gaba) possesses several physiological functions such as neurotransmission, induction of hypotension, diuretic and tranquilizer effects. production of gaba-enriched products by lactic acid bacteria has been a focus of different researches in recent years because of their safety and health-promoting specifities. in this study, glutamate decarboxylase (gad) gene of a loca...

In this study, 11 lactic acid bacteria (LAB) strains were screened for potential new probiotics using in vitro methods, including acid and bile salt tolerance, adhesion, antioxidative and a-glucosidase inhibitory activity. The results indicated that Lactobacillus casei 2W and Lactobacillus rhamnosus Z7 showed better potential probiotic properties and a-glucosidase inhibitory activity in vitro. ...

and Escherichia coli with a minus origin.

The members of the Lactobacillus genus are widely used in the food and feed industry and show a remarkable ecological adaptability. Several Lactobacillus strains have been marketed as probiotics as they possess health-promoting properties for the host. In the present study, we used two complementary next-generation sequencing technologies to deduce the genome sequences of two Lactobacillus case...
